AVCaptureSession and background audio iOS 7

Whenever I start an AVCaptureSession running with the microphone as an input it cancels whatever background music is currently running (iPod music for instance). If I comment out the line adding the audio input, the background audio continues.

Does anyone know a way to record video clips with the microphone while continuing to allow background audio to play? Also there is error, when you trying to record video and the music is currently playing.
